Description

The present invention relates to a Western-style toilet, and in particular, to a device that performs an appropriate cleaning operation according to the conditions of a trap drainage channel.

As a drainage structure for Western-style toilets, an on-floor drainage structure that connects the toilet drainage pipe to the drainage pipe provided on the wall of the toilet room and an underfloor drainage that connects the toilet drainage pipe to the drainage pipe provided on the floor Although it is known that the floor drainage structure requires more washing water to be used for transporting filth, both are usually washed with the same amount of washing water.
For this reason, in Western-style toilets with an underfloor drainage structure, more than the required amount of washing water is used, which is wasted water, and therefore a proposal has been made that the amount of washing water can be selected depending on the drainage structure. (For example, refer to cited document 1)

Japanese Patent Laid-Open No. 3-90744

Paying attention to the difference in the drainage structure of the trap drainage channel, changing the amount of washing water is effective in ensuring effective washing and eliminating wastewater as much as possible. However, there is room for improvement in the effective supply of cleaning water.
An object of this invention is to provide the western style toilet bowl which can supply an appropriate washing water according to the conditions of a trap drainage channel.

In order to achieve the above object, the invention described in claim 1 includes a ball that receives the excrement of a user, a trap drainage channel that seals the ball and the drainage pipe, and is connected to a drainage pipe disposed on or below the floor. In the Western-style toilet having a flush water supply means for supplying water for discharging waste water mixed with excrement to the drain pipe to the ball, the connection between the trap drain and the drain pipe is on the floor or in response to floor, have a cleaning sequence switching means capable of switching the operation of the washing water supply means to the cleaning sequence suitable therefor, the trap drainage channel is connected to the discharge pipe through the drain socket, the drainage socket has an information storage means, and transmits the information by combining the trap drainage, said cleaning sequence switching means is switched automatically And butterflies.

According to the present invention, the connection between the trap drainage channel and the drainage pipe switches the operation of the cleaning water supply means to a cleaning sequence suitable for the floor or the floor, so that the floor drainage structure is simply changed to the floor drainage structure as in the past. For example, it is possible to effectively wash the floor drainage structure with the same amount of flush water as the floor drainage structure, or to reduce the amount of flushing water in the underfloor drainage structure without requiring a larger amount of washing water. It is something that can be done. The cleaning sequence refers to a cleaning water supply step in which the toilet cleaning operation is divided into several steps. As a basic cleaning operation of the siphon toilet, when toilet cleaning starts, the cleaning water supplied from the cleaning water supply means first flows down toward the trap drainage while cleaning the bowl surface, and then When the trap drainage channel is filled with water, the siphon action is activated, and the siphon action discharges and conveys filth from the toilet, and when the siphon action ends, the discharge and transfer of filth ends and the supplied wash water The trapping drainage channel is sealed again to complete the cleaning operation.However, in the above process, the flow rate of the cleaning water required to start the cleaning water siphon operation and the flow rate of the cleaning water amount during the duration of the siphon operation are determined. In comparison, after the siphoning action is started, the force of the siphoning action is sufficient, so do not push the filth and so on toward the entrance of the trap drainage channel by supplying cleaning water. Since it is, the flow rate at the time of the siphon duration of action may be small. Therefore, it is possible to reduce the flow rate of the washing water when the siphon action is continued, and the amount of water can be reduced. Furthermore, in the floor drainage structure that requires a large amount of washing water to activate the siphon action, the reduced amount of water can be used for the washing water until the siphon action is activated without changing the total amount of water. Effective cleaning can be performed. In addition, since the drain socket is assembled at the construction site, the drainage socket can recognize the drainage structure on the floor or the drainage structure under the floor, so that the washing sequence can be changed reliably. In addition, the drain socket has information storage means, transmits information by combining with the trap drainage channel, and the washing sequence switching means is automatically switched, so that the floor drainage structure or the floor drainage structure is By storing the connection height of the drainage structure on the floor and the drainage core of the drainage structure under the floor along with the differences, even if the specifications vary depending on the construction site, the construction operator can perform optimal cleaning without special consideration. The sequence can be set and effective cleaning can be performed.

Furthermore, as a preferred aspect, the invention described in claim 2 has a notifying means for notifying the state of the cleaning sequence, thereby confirming whether the setting of the selected current cleaning sequence is error-free. Can do. In addition, in a site where the water saving possible by the ability of the toilet bowl is not possible due to administrative guidance, etc., specifically, it is a 6L toilet, but in a site where 8L cleaning is required, It is possible to confirm whether the instruction is instructed, and it is possible to change to another cleaning sequence according to the designation of the government.

Further, as a preferred aspect, the invention according to claim 3 is that the difference in the washing sequence is a difference in a partial operation time of the washing process and / or a difference in the water supply rate, so Depending on the amount of washing water, etc., the optimum amount of washing water in the washing process can be finely adjusted, so that the increase in the total amount of washing water can be suppressed as well as more effective while reducing the amount of washing water. Cleaning can be performed.

Further, as a preferred embodiment, the invention according to claim 4 is characterized in that the cleaning sequence includes a rim water discharging step for discharging water from the upper edge of the ball and a jet water discharging step for discharging water toward the trap drainage channel, thereby enabling the siphon action to be activated. It is possible to properly distribute the rim water discharge and the jet water discharge and the timing thereof while effectively using the effective water discharge.

  ADVANTAGE OF THE INVENTION According to this invention, the western style toilet which can supply an appropriate washing water can be provided by changing a washing | cleaning sequence according to the conditions of a trap drainage channel.

FIG.

  As shown in FIGS. 1 and 2, a Western-style toilet 1 according to an embodiment of the present invention is disposed so as to cover a toilet body 2, a toilet seat 4 disposed on the upper surface of the toilet body 2, and the toilet seat 4. A toilet lid 5 and a local cleaning device 3 disposed at the upper rear of the toilet body 2. Furthermore, a functional unit 10 is disposed behind the toilet body 2, and the functional unit 10 is covered with a side panel 10a.

The toilet body 2 is made of earthenware or resin, and the toilet body 2 has a ball portion 12 for receiving filth, a trap drainage channel 14 extending from the bottom of the ball portion 12, and a jet water outlet 16 for jetting water. And the rim spout 18 which performs a rim spout is formed.
The jet water spouting port 16 is formed at the bottom of the ball portion 12 and is disposed substantially horizontally toward the inlet of the trap drainage channel 14 so as to discharge cleaning water toward the trap drainage channel 14. It has become.
The rim water spouting port 18 is formed at the upper left rear of the ball portion 12 and discharges cleaning water along the edge of the ball portion 12.

  The trap drain 14 includes an inlet 14a, a trap ascending pipe 14b that rises from the inlet 14a, and a trap descending pipe 14c that descends from the trap ascending pipe 14b. The trap ascending pipe 14b and the trap Between the downcomer pipe 14c is a top portion 14d. The trap descending pipe 14 c is connected to the building through a drain pipe D and a drain socket 15, and the accumulated water mixed with excrement in the ball 12 passes through the trap drain 14 and the drain socket 15. , It will be discharged to the drainage pipe D.

  The Western-style toilet 1 according to the embodiment is directly connected to a water supply that supplies cleaning water, and the cleaning water is discharged from the rim spout 18 by the water supply pressure of the water supply. As for the jet water discharge, the wash water stored in the water storage tank built in the function unit 10 is pressurized by a pressure pump (not shown) and discharged from the jet water discharge port 16 at a large flow rate. .

FIG. 3 is an overall configuration diagram showing a Western-style toilet according to an embodiment of the present invention. With reference to FIG. 3, the functional part of the Western-style toilet according to the embodiment will be described in detail.
As shown in FIG. 3, the functional unit 10 includes a constant flow valve 20, an electromagnetic valve 22, a rim water discharge vacuum breaker 24, and a rim water discharge flapper valve 25. Further, the water supply path 19 includes a switching valve 28 for switching between water supply to the water storage tank 32 and rim water discharge, a water storage tank 32, a pressurizing pump 34, a jet water discharge vacuum breaker 36, and a jet water discharge flapper valve 38. A water drain plug 39 is incorporated. The function unit 10 includes a controller 40 that controls the opening / closing operation of the electromagnetic valve 22, the switching operation of the switching valve 28, and the rotation speed and operating time of the pressurizing pump 34.

  The said constant flow valve 20 is for restrict | squeezing the wash water which flowed in from the water inlet through the water stop cock 42a, the strainer 42b, and the branch metal fitting 42c below to a predetermined | prescribed flow volume. In the present embodiment, the constant flow valve 20 limits the flow rate of cleaning water to 16 liters / minute or less. The washing water that has passed through the constant flow valve 20 flows into the electromagnetic valve 22, and the washing water that has passed through the electromagnetic valve 22 is transferred to the rim water spouting port 18 or the water storage tank 32 by the switching valve 28. It comes to be supplied. The switching valve 28 can supply cleaning water to both the rim-side water supply path 18a on the rim side and the tank-side water supply path 32a on the tank side at the same timing, and the amount of water supplied to the rim side and the tank side. This is a switching valve that can arbitrarily change the ratio.

The electromagnetic valve 22 is opened and closed by a control signal of the controller 40, and the supplied wash water is caused to flow into the switching valve 28 or stopped.
Further, the switching valve 28 is switched by a control signal of the controller 40 so that the wash water that has flowed in via the electromagnetic valve 22 is discharged from the rim water spouting port 18 or flows into the water storage tank 32. It has become.

  The rim water discharge vacuum breaker 24 is disposed in the middle of the rim-side water supply path 18 a that guides the wash water that has passed through the switching valve 28 to the rim water discharge port 18, and allows the reverse flow of the wash water from the rim water discharge port 18. It is preventing. The rim water spouting vacuum breaker 24 is disposed above the upper end surface of the ball portion 12, thereby reliably preventing backflow. Further, the wash water overflowing from the air release portion of the rim water spouting vacuum breaker 24 flows into the water storage tank 32 through a return pipe 24a.

 The rim water spouting flapper valve 25 is disposed in the rim side water supply path 18a on the downstream side of the rim water spouting vacuum breaker 24, and prevents a backflow of cleaning water from the rim water spouting port 18. In the present embodiment, the rim water spouting vacuum breaker 24 and the rim water spouting flapper valve 25 are arranged in series in the rim side water supply path 18a, thereby preventing the backflow of cleaning water more reliably.

  The water storage tank 32 is configured to store wash water to be discharged from the jet water outlet 14. In this embodiment, the water storage tank has an internal volume of about 2.5 liters.

  Furthermore, in this embodiment, the front-end | tip (lower end) of the said tank water supply path 32a is opened to the position above the water storage tank 32, and the backflow from the said water storage tank 32 to the said tank water supply path 32a is prevented. . An upper end float switch 32b and a lower end float switch 32c are arranged inside the water storage tank 32 so that the water level of the water storage tank 32 can be detected. The upper end float switch 32b is turned on when the water level in the water storage tank 32 reaches a predetermined water storage level, and the controller 40 detects this and closes the electromagnetic valve 22. On the other hand, the lower end float switch 32c is turned on when the water level in the water storage tank 32 falls to a predetermined water level, and the controller 40 detects this and stops the pressurizing pump 34.

  A lid 32d is attached to the upper part of the water storage tank 32 so as to cover the opening at the upper end thereof, and the space between the outer periphery of the lid 32d and the inner wall surface of the upper part of the water storage tank 32 is watertight. It is joined. Further, the lid is provided with a circular hole, and the cylinder is attached so as to extend upward so as to surround the hole.

  Further, the wall surface of the water storage tank 32 extends above the lid body 32d, and the wash water overflowing from the cylinder of the water storage tank 32 accumulates on the lid body 32d. Further, a drainage passage 32f is connected to a wall surface above the lid 32d of the water storage tank 32 so that the washing water accumulated on the lid can be discharged to the ball portion 12. .

  The pressurizing pump 34 pressurizes the wash water stored in the water storage tank 32 and discharges it from the jet spout 16. The pressurizing pump 34 is connected by a cleaning water pipe 34 a extending from the lower part of the water storage tank 32, and pressurizes the cleaning water stored in the water storage tank 32. In the present embodiment, the pressurizing pump 34 pressurizes the cleaning water in the water storage tank 32 so that the cleaning water is discharged from the jet water outlet 16 at a maximum flow rate of about 120 liters / minute. It has become.

  Further, a jet water spouting flapper valve 38 and a water drain plug 39 which are check valves are provided in the middle of the washing water pipe 34a. The jet water spouting flapper valve 38 and the water drain plug 39 are disposed at a height near the lower end of the water storage tank 32 below the pressurizing pump 34. For this reason, by opening the water drain plug 39, the cleaning water in the water storage tank and the pressure pump 34 can be discharged during maintenance or the like. Further, when the jet water spouting flapper valve 38 is disposed between the water storage tank 32 and the pressurizing pump 34, the water level in the water storage tank 32 becomes lower than the height of the pressurizing pump 34. The washing water is prevented from flowing back from the pressurizing pump 34 to the water storage tank, so that the washing water in the pressurizing pump 34 is lost and the idling state is prevented when the pump is driven next time.

  On the other hand, the outlet of the pressurizing pump 34 is connected to the jet water spouting port at the bottom of the ball portion 12 through a washing water conduit 34b. In the middle of the washing water pipe 14, a convex shape is formed upward, and the washing water pipe top portion 44, which is the highest part of the convex part, extends from the water storage tank 32 to the jet water spouting port 16. It is the highest part of the irrigation water pipe.

  The jet water spouting vacuum breaker 36 is connected to a branch pipe 36a branched from the downstream side of the pressurizing pump 34 and the washing water pipe top 44, and the water stored in the ball part 12 is stored in the water storage tank 32. While preventing backflow to the side, the edge cutting between them is performed. Further, the washing water overflowing from the atmosphere opening portion of the jet water spouting vacuum breaker 36 flows into the water storage tank 32 through a return pipe 36b.

  The controller 40 sequentially operates the electromagnetic valve 22, the switching valve 28, and the pressurizing pump 34 by the operation of a toilet flushing switch (not shown) by a user, and the controller 40 is operated from the rim water spouting port 18 and the jet water spouting port 14. Water discharge is sequentially started to clean the ball portion 12. Further, the controller 40 opens the electromagnetic valve 22 after the cleaning is completed, switches the switching valve 28 to the water storage tank 32 side, and replenishes the water storage tank 32 with cleaning water. When the water level in the water storage tank 32 rises and the upper end float switch 32b detects a specified water storage amount, the controller 40 closes the electromagnetic valve 22 and stops water supply.

  The trap drain 14 communicates with the drain pipe D through the drain socket 15. 1 to 3 are examples of floor drainage (underfloor drainage structure). In the case of floor drainage, there is a drop of about 250 mm between the reservoir surface and the drainage pipe. On the other hand, when assuming wall drainage (floor drainage structure) with a drainage height of 120 mm, there is no drop of about 130 mm between the water surface and the drainage pipe. Naturally, the wall drainage has the same amount of washing water and the same washing sequence. And the discharge performance will be low. When the drainage height is 155 mm, the discharge performance further decreases. Even in the case of floor drainage, when the drainage position is 200 mm from the rear wall and 540 mm from the rear wall, the shorter the bending distance from the rear wall, that is, 200 mm, the lower the discharge performance. The difference in discharge performance is due to the drop between the reservoir surface and the drainage pipe. The larger the drop, the greater the potential energy, so the siphon action tends to occur.The smaller the drop, the smaller the potential energy, and the siphon action. It happens because it is hard to happen. In addition, the shorter the bend distance from the rear wall, the smaller the volume filled with water, so that the strength of siphon action may be lower than when the distance is long.

  Moreover, it is conceivable that the decrease in the discharge performance is due to the delay in the activation of the siphoning action due to the poor efficiency of supplying the washing water to the trap drainage channel, or the siphoning action is weak. Therefore, by increasing the pump rotation speed and increasing the instantaneous flow rate of the jet discharge in a short time, the cleaning water supply efficiency can be increased so that the trap drainage can be filled quickly. The siphoning action can be activated at the same timing as when the discharge performance is high without increasing it. After starting the siphon operation, it is sufficient to supply wash water to the extent that the siphon operation does not stop, so the rotation speed is reduced.For example, the pump rotation speed and rotation time are optimal to maintain the siphon operation, and the amount of wash water is reduced. Cleaning can be performed effectively without increasing the number.

  The drain socket 15 incorporates flow detection means and / or information storage means whose configuration will be described later. The controller 40 has a built-in washing sequence switching means obtained from the flow detection means and / or the information storage means. By selecting a washing sequence that distributes the optimum water amount to the rim and the jet, the washing water loss is reduced. Effective cleaning that prevents the occurrence of In addition, the operation of manually switching the washing sequence is arranged to prevent the occurrence of poor washing and loss of washing water due to work mistakes.

FIG. 4 is a system block diagram of a Western-style toilet according to an embodiment of the present invention. The linking operation of each part will be described in detail using FIG.
The Western-style toilet 1 of the present invention is roughly divided into a toilet body 2 and a controller 40. The controller 40 incorporates a washing sequence switching means 40a and an operation / display means 41. The operation / display unit 41 receives a toilet cleaning operation signal, transmits predetermined cleaning sequence information to each unit, and performs a notification operation 41a for notifying the setting contents of the cleaning sequence and an operation for changing the cleaning sequence. The setting change means 41b is incorporated. When the user performs the toilet cleaning operation from the operation / display means 41, the controller 40 sequentially operates the cleaning water supply means 6, the flow path switching means 7, the cleaning water storage means 8, and the jet water supply means 9, and the ball portion 12 Wash. Water is supplied from the rim water outlet 18 and the jet water outlet 16 at a predetermined timing, a water supply rate, and a water supply time, and the waste water mixed with excrement is discharged to the drain pipe D through the trap drain 14 and the drain socket 15. Will be.

  In the cleaning, it is changed depending on the conditions of the trap drainage channel. For example, in the initial setting, the cleaning sequence is suitably set for wall drainage with severe drainage conditions, so at the floor drainage site, the construction operator can change the setting to a cleaning sequence suitable for floor drainage. Clean operation is performed. At this time, since it is possible to select a cleaning sequence according to the connection height with the drain pipe, an appropriate cleaning sequence is selected according to the selection. When using a drain socket, it is easy to judge whether it is floor drainage or wall drainage by its appearance.

  In addition, an appropriate washing sequence is selected while detecting the flow state built in the drain socket 15 by the flow detection means 15a, or floor drainage or wall drainage according to information in the information storage means 15b built in the drain socket 15. Or the drainage height or drainage core position is confirmed, and the washing sequence switching means switches the washing sequence to an appropriate content. The information storage means 15b may be provided in the controller 40. Even if the cleaning sequence is changed depending on the specifications of the drain socket, cleaning may not be performed according to the user's request. In addition, it may be necessary to change the amount of washing water depending on the required specifications of the sewer. For such cases, it informs what the current cleaning sequence is. The notification means is attached to the toilet seat. As a manual switching method of the cleaning sequence, the cleaning sequence is switched by an auxiliary operation switch (not shown) attached to the local cleaning device 3. The notification means may be notified by LED or buzzer. If the LED issuance pattern and buzzer pattern are determined in accordance with the cleaning sequence, a setting error is not made for those performing the switching operation.

  The washing sequence has multiple tables in advance depending on the conditions of floor drainage, wall drainage, the height of the connection between the trap drainage channel and the drainage pipe, the drain core length, and the flow state of the trap drainage channel. In operation, it may be set after confirmation. However, when the drain socket or the like has storage means, it is automatically set as described above.

Next, a cross-sectional view of the Western-style toilet in the embodiment of the present invention described above will be described. FIG. 5 is a cross-sectional view of the Western-style toilet of the present invention.
A switch that is switched by combining the toilet body 2 and the drain socket 15 is provided at a portion connecting the drain socket 15 and the trap drain 14. When the changeover switch 15c detects the presence of the drain socket 15, it is detected that the drain direction is the floor. The changeover switch 15d is a switch for detecting the wall drainage height, and the washing sequence is changed in consideration of the change in the discharge capacity depending on the discharge height. As a method for detecting the wall drainage height, an encoder type detection or a sensing method such as a Hall IC may be used. If the above-mentioned changeover switch 15c is not a simple ON / OFF switch but adopts an encoder type detection method, the washing sequence is changed in consideration of the change in the discharge capacity at the drainage core. This detection can be automatically switched by combining the toilet body 2 and the drain socket 15 at the time of construction. The information storage means 15b is realized by the difference in outer shape of the drain socket 15 or by specifically incorporating dimensional information.

  Further, the pressure sensor 15e may be used to automatically determine the specification of the drain socket. The toilet is discharged due to a difference in pressure between the atmospheric pressure and the drain socket 15, but the outflow state can be estimated in a state where the pressure difference is generated. The pressure sensor 15e is a representative example of the flow detection means 15a. In consideration of the atmosphere in the drain pipe, a semiconductor pressure sensor is recommended as the pressure measurement method. When the siphon is activated, the pressure in the drain socket suddenly generates a negative pressure. In the case of floor drainage, when a siphon occurs, negative pressure is generated more rapidly than in the case of wall drainage. Therefore, it is possible to determine whether it is floor drainage or wall drainage by looking at the inclination when negative pressure is generated. In addition, floor drainage is faster than siphon activation than wall drainage. Therefore, floor drainage and wall drainage can be distinguished by detecting the time until the predetermined pressure is reached. Furthermore, it is possible to determine the level of pressure at a predetermined time and discriminate between floor drainage and wall drainage.

Next, the cleaning sequence in the above-described embodiment of the present invention will be described. FIG. 6 is a time chart comparison of cleaning sequences of the present invention for floor drainage and wall drainage. The horizontal axis of the graph is the elapsed time, and the vertical axis is the water supply rate per unit time.
The activation time and strength of siphon action vary depending on the drainage type and specifications. In the case of floor drainage, the siphon action is strong and durable. Moreover, since the siphon action is activated quickly, the amount of water required to activate the siphon action is small. In the case of wall drainage, compared to floor drainage, siphon action is weaker and there is no sustainability. Also, since activation is slow, it is necessary to use a lot of water to activate the siphon action. There is a difference in siphon action depending on the form and specifications of such drainage, so it is necessary to efficiently distribute water to the rim and jet. Specific constants to be changed are the rim water discharge time and the rotation time of the pump rotation speed pump.

  Ry1 and Rk2 are the front rim times of floor drainage and wall drainage. The front rim vents the air remaining in the toilet pipe by raising the water level of the water in the ball 12, and also raises the head by raising the water level to make the siphon action easier to occur. There is a role. For this reason, in the case of wall drainage in which siphon action is unlikely to occur, the front rim time is made longer than in the case of floor drainage (for example, Ry1 <Rk1).

  The jet then activates the siphon action and has the role of discharging the waste into the drainage pipe. Jy and Jk are jet times of floor drainage and wall drainage, respectively. In the case of wall drainage, the siphon action is weakly activated, so the pump rotation time is lengthened and the waste is pushed out into the drainage pipe (for example, Jy <Jk). Ny and Nk each indicate the number of rotations of the pump. In the case of wall drainage, since the activation of the siphon action is slower than in the case of floor drainage, the rotation speed is increased and the siphon action is activated earlier (for example, Ny <Nk).

  Finally, the rear rim time will be described. Ry2 and Rk2 in FIG. 6 are post-rim times of floor drainage and wall drainage, respectively. The rear rim serves to seal the ball 12 in order to prevent the generation of odor from the drain pipe. In the case of floor drainage, the siphoning action is strong and durable, so when the siphoning action ends, a lot of water is discharged into the drainage pipe, and there is little remaining water, so it is necessary to lengthen the rim time to seal the water ( For example, Ry2 <Rk2).

FIG. 7 is one example of a flow chart of a Western style toilet bowl embodying the present invention. The operation of the Western-style toilet in the above-described embodiment of the present invention will be described. In the changeover switch system, the cleaning sequence is uniquely determined by the detection state, but this embodiment shows a method of detecting the flow state and changing the cleaning sequence.
The determination sequence starts with the first cleaning after construction (S101). First, cleaning is performed in a wall draining sequence (S102). When the washing switch is pressed (S103), the water passes through the toilet and flows into the drain socket. At that time, pressure state detection is started (S104). The result is transmitted to the information storage means and the cleaning sequence switching means. The cleaning sequence switching means performs determination (S105). After confirming the result, the cleaning sequence is switched to the floor draining sequence or the wall draining sequence (S106, S107). After the next time, cleaning is performed in the switched cleaning sequence. Although selection only at the time of construction is common, since the state of the drain piping may be changed depending on the state of the building, it may be appropriately implemented in the maintenance mode.

  In the above-described embodiment, the toilet with pump water supply is excellent in that it can cope with various washing sequences by changing the water supply rate widely by changing the number of rotations of the pump. A Western-style toilet that uses water pressure directly may be used.

  Moreover, in the said embodiment, since the siphon effect | action can be started at an early stage, it demonstrated with the siphon zette toilet bowl, However, A siphon toilet bowl without a zette may be sufficient. In the case of a siphon toilet, the water level rises to some extent and the drain pipe is full, and the siphon action starts, but if the water level rises more than necessary, the swirl flow with the filth in the ball spreads, Since there is a problem that the siphoned action is activated by diffusing dirt around the periphery of the bowl and the water level is left behind at once, it is desirable to adopt a cleaning sequence that takes into account the rise of the water level and the activation of the siphon action.

  In the present embodiment, the Western-style toilet having a drain socket has been described, but the present invention can also be applied to a trap drain connected directly to a drain pipe.

It is a side view which shows the western style toilet bowl by embodiment of this invention. It is a top view of the western style toilet bowl of this invention. It is a whole block diagram which shows the western style toilet bowl by embodiment of this invention. It is a system block diagram of the Western style toilet bowl in embodiment which implemented this invention. It is sectional drawing of the western style toilet bowl of this invention. It is a time chart comparison of the washing | cleaning sequence of this invention. It is one Example of the flowchart of the western style toilet bowl which implemented this invention.
